SIGNAL.

SPECIFICATION forming part of Letters Patent No. 273,218, dated February27, 1883.

Application tiled May 6` 1882. (No model.) l

T 0 all whom fit may concern Beit known that I, JOSEPH H. BAcoN, acitizen of thc United States, residing at Charlotte, in the county ofEaton and State of Michigan, have invented a new and usefulalldirections; second, to insure certainty as to the color of lightintendedto he shown; third,

to prevent the light being jerked out or put out byrapidrevolvingofthelamp; and,i`ourth, to ait'ord facilities in the rapidityand certainty of the operation of signals. I attain these objects by themechanism illustrated in the accompanyingl drawings, in which- Figure lis a detailed view in perspective of the signal ready for operation,connected with the mechanism intended to operate the same, the otherviews constituting the mechanism intended to operate the signal, Fig. 1,and consists of the separate base S, the slide W, the lever N, thecog-wheel A, the notched bars C and B, the guide K, and the rods J andH, and the set-screw e, said parts being shown detached.

Similarlettcrs refer to similar parts thron ghout the several views.

The top R, the base I, the standardsa a a c, extending from R to I,together with a partition upon which sets the lamp L, and which isconnected to a ct c a. at b b' b, Fig. l, constitute the framework of myinvention. The shield F completely encircles the standards a a a a,which serve as a guide. The shield F is also provided with a door, 3, toadmit of ready access to adjust and tend to the lamp L within, and ismade to slide readily up and down the standards c a tt a. The shield Fis further provided with an ear or loop, m, for receiving the rod f,used for connecting the shield F with the machine used in operating it.The shield F is constructed of thin sheet or galvanized iron, and isprovided with holes 5 5 5 through which passes air to the lamp L afterclosing the door 3.

The block X supports the signal, as shown in Fig. 1, and is securedtothe projection or fore-arm P by means of bolts, as at 4 4, andis broadenough on the top to receive the base I. The block X, which supportsthedevice, being thus securely attached to P, Italie the base I,

which is either wood or iron, large enough to fully cont-ain the bottomof an ordinary lantern, and fasten it, by means of screws 8 8, to theblock X. The rods or standards ct a, a a are then screwed or fastenedperpeudicularly into l at 9 9 9 9. and a partition constructed ot' thinsheet metal is permanently secured to a ct rt a at b b b, midway betweenthe top Rand base I, attached by any desirable method, or by solder orscrews at b b b. I now put on the shield F over the standards a a a a,being loose enough to readily move, after which I permanently secure totop R on the ends of a c a a, R having holes through the corners at b bb b for receiving a a a a, and the rodsot a c a having a small shoulderon the top ends for receiving and permanently holding R, and to admit ofriveting; or small nuts maybe screwed on the ends. I now place a lamp orlantern, G, containing red light on the base I, also a lamp or lantern,L, showing a white light on the partition between the top R and the baseI, and attach the connecting-rod f to the shield F at m. f

For operating the device shown I take the base S and bolt or screw it onthe operators table Z at g g g. Then I take the slide W and place it onthe top of S, S being groovedto admit the circular slide W, after whichthe lever N is placed over thehub o' ot' W and fastened to W by thescrews p p. The setscrews e and c being screwed into S to regulate thelever N, 1 now put the rod H in the hub i* of the slide W and secure itso as not ,to turn, except with the slide W, by means of the set-screwe, screwed into the hub fr, securely holding the rod H. The cog-wheel(three of which are used in this machine, all being similar) A is castwith a hub, s, and attached to the top of the rod H, also secured by aset- I now take the rod J and at one end attach, by means of theset-screw e, the notched bar C, which meshes into the cogwheel A,attached to H, being held in proper IOO Q @tenete position by meansofthe guide K, xed to the board P. At the other end of J, alreadymentioned, I attach, by means of the set-screw e, the bar B, notched ontwo adjacent sides,"as shown. The barB is held in position by means ofthe guide K, attached to P, extendingfrom the building which supportsthe signal F. The wheel A under the signal meshes into one side of thenotched bar B, and has a quarter-turn by the device shown. Another WheelA also meshes into the top ofthe notched bar B, and is secured to theblock X by means of a journal, h, attached to block X. The verticalwheel A has an arm, V, attached to it at 7a, and contains a hole, n., atone end, through which passes the end ot' the connectingrod f, the endof j' being turned or bent at right angles, so as to Work like an axlethrough the hole in the end ot' the arm V. The target T is secured intothe hub of the horizontal wheel A under the signal F, supported` by theguide K, by means of the set-screw c. I now take hold ot'theleverN at E,which passes over the base S from the set-screw c, (6 and c being ofdit'erent color, so as to serve as an indicator,) and move itquarter-way round to e', thus turning the cog-wheel A quarter-Way round,which causes the shield F to fall and the target T to turn.

Having thus described my invention, claim- 1. The combination of a casesupporting two stationary lights of different colors, a sliding opaqueshade to obscure one of said lights when it discloses the other, andsuitable gearing to operate the same from within the station-house,substantially as set forth.

2. The combination of a case supporting two stationary lights ofdifferent colors, a sliding opaque shade to obscure one ot' said lightswhen it discloses the other, suitable gearing to operate the same fromwithin the station-house, and a rotating day signal operated in unisonwith said shade, substantially as set forth.

3. The combination, with a case supporting two stationary lights ot'dit't'erent colors, of a sliding opaque shade to obscure one ot' saidlights when it discloses the other, said shade having perforations toadmit air for the purpose of combustion, substantially as set forth.

4. The combination ot' stationary lights of different colors, the shadeF, the gears A, racks B and C, rods J H, stand S, slide W, lever N, andstops c a', substantially as set. t'orth. n
